Title: How to Properly Call and Use the cosh Function for Calculations in the Laravel Framework<br>
*/</p>
<p>// Laravel is a popular PHP framework. When handling mathematical calculations, developers sometimes need to use the hyperbolic cosine function cosh().<br>
// This article will explain in detail how to properly call and use the cosh() function in Laravel.</p>

<li>
<p>Native PHP cosh() Function</p>
</li>
</ol>
</li>
<li>
<p>PHP provides a native cosh() function that takes a float or integer as a parameter and returns its hyperbolic cosine.</p>
</li>
<li></li>
<li>
<p>Syntax:</p>
</li>
<li>
<p>float cosh(float $number)</p>
</li>
<li></li>
<li>
<p>Example:<br>
*/<br>
$number = 2.0;<br>
$result = cosh($number);<br>
echo "The hyperbolic cosine of number {$number} is: {$result}<br>";</p>
</li>
</ul>
<p>/**</p>

<p>2. Using cosh() in a Laravel Controller</p>
</li>
<li>
<p>Suppose we need to calculate a hyperbolic cosine value inside a Laravel controller:<br>
*/</p>
</li>
</ul>
<p>namespace App<span>Http</span><span>Controllers</span>;</p>
<p></span>use Illuminate<span>Http</span><span>Request</span>;</p>
<p></span>class MathController extends Controller<br>
{<br>
</span>public function calculateCosh(Request $request)<br>
{<br>
</span>// Get number from request<br>
$number = $request->input('number', 0);</p>
    </span><span><span class="hljs-variable">$coshValue</span></span> = <span><span class="hljs-title function_ invoke__">cosh</span></span>(<span><span class="hljs-variable">$number</span></span>);

    </span><span><span class="hljs-comment">// Return result to view or as JSON</span></span><span>
    </span><span><span class="hljs-keyword">return</span></span> <span><span class="hljs-title function_ invoke__">response</span></span>()-&gt;<span><span class="hljs-title function_ invoke__">json</span></span>([
        <span><span class="hljs-string">'number'</span></span> =&gt; <span><span class="hljs-variable">$number</span></span>,
        <span><span class="hljs-string">'cosh'</span></span> =&gt; <span><span class="hljs-variable">$coshValue</span></span>,
    ]);
}

}

/**

3. Displaying cosh Results in a Blade Template
If you want to show the calculated result in a frontend template, you can do this:
*/

// Assume $coshValue has already been passed from the controller to the view
?>

The hyperbolic cosine of number {{ $number }} is: {{ $coshValue }}

<?php
/**

4. Notes
- The parameter for cosh() must be numeric, otherwise a warning will be thrown.
- For large values, the result can be extremely large, so watch out for data type overflow.
- In scenarios involving heavy math operations, you may also consider using Laravel services or custom helper functions for unified handling.
  */

/**

Summary:
Calling cosh() in Laravel is very straightforward since Laravel fully supports PHP native functions.
You just need to call cosh() directly in a controller or service class, then return the result to the frontend or other business logic.
